TO ALL WHOM IT MAY CONGERN Be it known that I, B. B. PERKINS, of Chestertown, in the county of Kent, and State of Maryland, have invented a new and improved Combined Boiler and Hot-Air Register; and I do hereby declare the following to be a. full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specication, and in which- Figure 1 is a top view of my invention.

Figure 2 is a. vertical section oftthe same, through the line :v x in iig. 1.

Similar letters of reference indicate corresponding parts in the two gures.

In this invention, a boiler connected with the register is attached to the side or end `of the hot-air lucsin houses, for the purpose of utilizing the heat conducted awa-y by the walls i the ilues, and of supplying hot water to the upper rooms of the house.

In order that others skilled in the art to which my invention appertains may beenabled to make and use the same, I will proceed to describe it in detail.

In the drawings, A A represent a hot-air flue, extending from the heating-urnnce4 to thenpper part ot' a house, and discharging its heated air into the room, through the register B. At.C, I locate a boiler, having a. spigot at D, and a lid at E, through which the boiler may be filled or emptied. I provide several apertures, e e e e, in the top of myboiler, and attach to it a movable cover, F, swinging horizontally o n o. pivot, f, and

havin holes which as the cover is moved in one direction or another will be broufrht into or thrown out D J 7 a a o of connection with the holes e e e in the top of' the boiler. When open, the steam will escape through them and meisten the hot'air supplied to the room through thc register, for the purpose of-making it more wholesome.

`The covermay be connected by a coril or wire II to the register, so that in proportion as the register is opened the apertures e e will also be opened, and the escape otsteain ir`1to `the fiue be exactly proportionedto the quantity of hot air used in the room. i

Having thus described my invention, what I claim as new, and desire to secure by Letters Potent, is-

Inconnection with a boiler, arranged at the top or side of' hot-air ilues in houses, the combination and arrangement of the perforated boiler-top'witli the perforated cover F, pivoted at f, the connecting-rod H, and the register B, when the parts referred to ure constructed and arranged substantially in `the manner nl' d for the purposes set iorth. l
